Brain-computer interfaces can provide a new communication channel and control functions to people with restricted movements. Recent studies have indicated the effectiveness of brain-computer interface (BCI) applications. Various types of applications have been introduced so far in this field, but the number of those available to the public is still insufficient. Thus, there is a need to expand the usability and accessibility of BCI applications. In this study, we introduce a BCI application for users to experience a virtual world tour. This software was built on three open-source environments and is publicly available through the GitHub repository. For a usability test, 10 healthy subjects participated in an electroencephalography (EEG) experiment and evaluated the system through a questionnaire. As a result, all the participants successfully played the BCI application with 96.6% accuracy with 20 blinks from two sessions and gave opinions on its usability (e.g., controllability, completeness, comfort, and enjoyment) through the questionnaire. We believe that this open-source BCI world tour system can be used in both research and entertainment settings and hopefully contribute to open science in the BCI field.
脑机接口可以为行动受限的人提供新的通信渠道和控制功能。最近的研究表明了脑机接口（BCI）应用的有效性。到目前为止，该领域已经引入了各种类型的应用，但面向公众的应用数量仍然不足。因此，有必要提高BCI应用的可用性和可及性。在本研究中，我们介绍了一款BCI应用，供用户体验虚拟世界之旅。该软件基于三个开源环境构建，并可通过GitHub代码库公开获取。为了进行可用性测试，10名健康受试者参与了脑电图（EEG）实验，并通过问卷调查对系统进行了评估。结果，所有参与者都成功地使用该BCI应用进行了操作，两次测试中眨眼20次的准确率达到了96.6%，并通过问卷对其可用性（如可控性、完整性、舒适度和趣味性）发表了意见。我们相信，这个开源的BCI世界之旅系统可用于研究和娱乐场景，并有望为BCI领域的开放科学做出贡献。
